• See [BUG] Jaeger Hotrod demo does not work #2273 (comment) .
• Starting from Use OpenTelemetry SDK in HotROD 🚗 jaegertracing/jaeger#4187, Jaeger HotROD no longer uses jaegertracing/jaeger-agent to receive jaegertracing/example-hotrod data, but directly uses otel/opentelemetry-collector-contrib. According to https://www.jaegertracing.io/docs/1.60/deployment/#agent , jaegertracing/jaeger-agent is considered a deprecated component. It does not make any sense.
• According to https://opentelemetry.io/docs/collector/installation/ and https://opentelemetry.io/docs/collector/deployment/agent/ , removing the use of the Jaeger Agent is very simple.

#4921 does not actually remove the dependency on jaeger agent. Should I update my PR?
